What Are Sparklines in Excel?

Sparklines are small, condensed charts that fit into a single cell. In Excel, sparklines provide a quick visual representation of original data such as trends, patterns, growths, and variations.

The best feature of Sparklines is that it explains data without the need for a full-size chart while remaining in the background of a cell.

Sparklines were introduced in Excel 2010 and are now available in all later versions of Excel.

Why Use Sparklines in Excel?

Generally, professionals use sparklines in Excel to get a quick overview of data over time in areas such as sales, stock prices, performance metrics, trend calculation, temperature fluctuations, and more. Typically sparklines are placed next to the rows or columns of data. As a result, users get a quick concise snapshot of the data trend in each row or column.

Although Sparklines do not offer detailed information like standard graphs and charts, their advantages lie in being compact, providing a quick assessment, and for smooth integration with the data tables.

Besides, Sparklines saves space on the workbook and enhances the readability of data. Changing the data in Excel will automatically update the Sparklines, making them dynamic and efficient.

How Many Types of Sparklines Are Available in Excel?

In Excel, there are 3 types of sparklines. Each with its usages and features. Check the following section for more details.

i. Line Sparklines

Line Sparklines represent data trends using a simple line graph within a single cell. It’s ideal for displaying data trends over time. For example, stock prices, temperature fluctuations, performance evaluation, etc.

For example, we have shown monthly sales revenue trends of 5 products in line sparklines for 5 months.

ii. Column Sparklines

Column Sparklines use vertical bars to visually represent variations in data within a single cell. You can create column sparklines to compare individual data points across categories or time intervals. Suited for comparing discrete values such as sales figures, performance metrics, etc.

In the following image, we have compared the monthly sales revenue of each product using Column Sparklines.

iii. Win/Loss Sparklines

This specific type of sparkline represents positive (win) or negative (loss) outcomes using symbols. Best for showcasing binary data or outcomes. Such as monthly goal achievements, project milestones, or game scores, where the focus is on success or failure. You can use win/loss sparklines to provide a quick clear visual distinction about whether the goal is achieved or not.

Check out the image below, showing the weekly attendance of 5 students. The red signs indicate absences or -1.

How to Add Sparklines in Excel?

You can add sparklines in Excel using the Insert tab. To create sparklines you can navigate to the Sparkline group where you will find all the available sparklines. There are two ways you can add sparklines in Excel.

i. Add Sparklines in Individual Cells

To add sparklines in individual cells, follow these steps:

• First select the cell where you want the sparklines, i.e. Cell H6.
• Go to the Insert tab ⇒ Sparklines group ⇒ Choose a type (e.g., Line Sparklines).
• In the Create Sparklines window, select the Data Range (e.g., C6:G6).
• Verify that the Location Range is set to $H$6.
• Click OK to create line sparklines based on the specified data.

• You can also use the Fill Handle feature to autofill the remaining cells.

ii. Add Sparklines to Multiple Cells

If you want to add sparklines to multiple data ranges, you can use the following steps instead.

• First select the cell range where you want the sparklines, i.e. Cell H6:H10.
• Head to the Insert tab ⇒ Sparklines group ⇒ Choose a type (e.g., Line Sparklines).
• In the Create Sparklines window, select the Data Range (e.g., C6:G10).
• Verify that the Location Range is set to $H$6.
• Click OK to create line sparklines based on the specified data.

You can check out the Monthly Trend column (H6:H10) which has line sparklines for each row showing individual data trends. Thus, you can easily create sparklines for multiple cells.

How to Customise Sparklines in Excel?

You can customize sparklines by navigating to the Sparkline tab from selecting individual or group sparklines. Excel provides extensive customization options, allowing you to modify the appearance of lines or bars and finely tune axis settings. Additionally, you can highlight specific key points within the Sparklines. Check the following section for details.

i. Change Sparklines Type

To change the sparklines type, follow these simple steps.

• Select the sparkline or group of sparklines
• Head to the Sparkline tab
• Under the Type group, choose any.

ii. Change Style and Color

You can quickly change the sparkline style and color by accessing the Style group in the Sparkline tab.
Simply choose any of the available colorful styles from the drop-down menu of the Styles section. Moreover, you can use the Sparklines Colors drop-down menu to manually change Sparklines color.

iii. Change Line Width

Adjust the line width of sparklines easily by selecting thicker or lighter options in the Weight section under sparkline color. Follow these steps for a swift modification of sparkline line width.

Select the sparkline ⇒ Sparkline tab ⇒ Style group ⇒ Sparkline Color drop-down menu ⇒ Weight option ⇒ Select any weight to change the line width.

iv. Change Axis Options

You can also change and get more access to the figure by simply navigating the Axis options under the Sparkline tab. Generally, Excel sparklines do not use any axis or coordinates. They plot the lowest value of the dataset at the bottom, with other points positioned relative to it. However, Excel provides the flexibility to use the axis when necessary.

Horizontal Axis Options
This feature usually signifies categories or time intervals. Using this feature you can customise different aspects of Horizontal Axis.

• General Axis Type
  It automatically detects the general type of horizontal axis in sparklines representing categories or time intervals based on the data.
• Date Axis Type
  If your data has date values, you can select this feature to choose the date data for the horizontal axis value.
• Show Axis
  It shows the horizontal axis within the sparkline. By default, it remains hidden.
• Plot Data Right to Left
  Useful for scenarios where you need to present data in reverse order (from right to left).

Vertical Axis Options
The vertical axis in Sparklines signifies data values. Customize this axis by setting minimum and maximum values to ensure a precise reflection of the data range. It has the same options for minimum and maximum values.

• Automatic for Each Sparkline
  Sets the minimum or maximum value of the vertical axis independently for each Sparkline.
• Same for All Sparklines
  To ensure consistency and maintain a standard scale, it sets a uniform value for the vertical axis across all sparklines to simplify the comparison.
• Custom Value
  It allows users to define a specific value for the vertical axis by giving precise control over the data range.

For instance, if the variation between the lowest point and other values seems larger than actual, you can use the options under the Vertical Axis.

This allows you to set maximum and minimum values using the Custom Value option, providing a more accurate representation of the data trend in the sparkline.

v. Highlight Data Using a Marker

Using the options under the Show group of the Sparkline tab you can easily highlight data based on Sparklines type. Excel offers the opportunity to highlight specific notes to make the figure more informative. It has the following options.

• High Point: Displays the highest point or maximum values within the sparklines.
• Low Point: It highlights the lowest point or minimum values within the sparklines.
• First Point: Highlights the first point in the figure.
• Last Point: It marks the last point at the end of the data series
• Negative Points: This option shows the values that are below zero.
• Markers: Selecting this option will enhance the clarity of the sparklines by highlighting individual data points.

In the case of Line sparklines, you can add Markers to sparklines to point out data.

For column sparklines, you can use the High Point and Low Point to make the column sparkline more meaningful by providing important details.

How to Group and Ungroup Sparklines in Excel?

To group or ungroup sparklines in Excel, you can use the Group options from the Sparklines tab of the Excel ribbon. When you create sparklines in Excel, choosing an individual cell or the entire range of the sparklines activates the Sparkline tab on the Excel ribbon.

Check the following steps to group sparklines in Excel.

• Select the cell range you want to group (i.e. H6:H10).
• Navigate to the Sparkline tab ⇒ Locate the Group options at the rightmost corner ⇒ Choose Group.

This action will group multiple sparklines at once.

If you want to ungroup sparklines, check these steps.

• Select the group range you want to ungroup (i.e. H6:H10).
• Head to the Sparkline tab ⇒ Group options ⇒ Choose Ungroup.

How to Show Sparklines for Hidden and Empty Cells?

To show sparklines for hidden and empty cells in Excel, you can use the Hidden & Empty Cells option by navigating to the Edit Data drop-down menu from Sparkline tab. When a sparkline dataset has hidden rows or columns or empty cells, It does not show continuity for missing data. In Excel, sparklines are designed to accurately represent the available data without making any assumption about the values of missing data.

You can use the following steps to treat your broken sparklines.

Select the sparkline or group ⇒ Sparkline tab ⇒ Edit Data drop-down menu ⇒ Select Hidden & Empty Cell… option.

From the Hidden and Empty Cell Settings window you will have the following options.

• Gap
  This option will display the break in the sparline if there is hidden data or missing value in the cells.
• Zero
  It treats hidden data or missing values as zero. Thus, it maintains the continuity of the sparkline by plotting zero as a substitute value.
• Connect data points with Line
  It ignores the hidden and empty cells by creating a bridge between the gaps. It instructs Excel to connect sparlines across the hidden data or empty cells.

Show data in hidden rows and columns
By default, this option is disabled as sparklines only consider visible data. If you enable this option, it will include data from hidden rows and columns when rendering for visualization.

If your data has only hidden rows or columns, not missing values, selecting this option will allow sparklines to maintain continuity. Using these options you can easily solve the issue of sparklines not showing in Excel.

How to Resize Sparklines in Excel?

You can resize sparklines in Excel by changing the size of the cell. To enhance your visual representation you can resize sparklines using these steps.

• If you want to change the height of sparklines, adjust the rows. Either make it taller or smaller.

• If you want to change the width of sparklines, adjust the columns. Make it wider or narrower.

How to Remove Sparklines in Excel?

You can remove sparklines in Excel from the Sparkline tab in the top ribbon which appears after selecting the sparklines. Check the following steps.

Select the sparklines ⇒ Sparkline tab ⇒ Group Option ⇒ Clear Drop down menu.

In the Group option, under the drop-down menu of Clear, you will find 2 options. You can clear the selected sparklines by selecting Clear Selected Sparlines or the entire group by selecting Clear Selected Sparkline Group.

Or else you can use this method.

Home tab ⇒ Editing group ⇒ Clear drop-down menu ⇒ Clear All.
